Collins told jurors earlier this week that if they were unable to reach a verdict on the second-degree murder charge, they had the option of convicting Swartz of lesser charges of "voluntary" or "involuntary" manslaughter.

The main question jurors must decide is whether Swartz was justified in firing 16 shots at Elena Rodriguez in the span of 34 seconds, in response to the teen throwing rocks over the fence during a botched drug-smuggling attempt.

Defense attorney Sean Chapman argued the Border Patrol agent made a "split-second decision" to use deadly force because he believed an agent and a Nogales police dog had been hit by rocks, even though witness testimony contradicted those claims.

Prosecutors argued that the use of force was "unlawful." They claimed neither Swartz nor any of the agents and officers on the scene that night were in real danger, and that firing 16 shots, including 10 to Elena Rodriguez's head and back, was excessive.

The trial began earlier this month, more than five years after the shooting.
